Abstract
The utility model belongs to the technical field of a foundation pit of an elevator shaft, relating to a supporting structure of a pine pile of a foundation pit of an elevator shaft. Pine pile guard rails are vertically arranged on the peripheral wall of the foundation pit of the elevator shaft at intervals; the bottom of the foundation pit of the elevator shaft in the pine pile guard rails is paved with a stone cushion layer; the stone cushion layer is poured with a concrete cushion layer; the inner wall which is formed along the pine pile guard rails in the foundation pit of the elevator shaft is built with a brick wall fence; the place of a half height of the brick wall fence is provided with a concrete ring beam; the gaps between the brick wall fence and the pine pile guard rails are filled with filling materials; and the upper ends of the brick wall fence and the pine pile guard rails as well as the upper periphery of the foundation pit of the elevator shaft are poured with top pressing concrete. The structure has the advantages of low cost, short work period, good safety performance and environment protection, and is suitable for the elevator shaft, the depth of which is within 2-4m.
Description
Technical field
The utility model belongs to elevator shaft foundation ditch technical field, refers in particular to a kind of elevator shaft foundation ditch supporting pine pile structure.
Background technology
Development along with the foundation pit construction technology, going along with sb. to guard him of basement foundation ditch correspondingly is tending towards safe and perfect, domestic and international existing elevator shaft foundation pit supporting construction generally all adopts the soil nailing wall type structure, utilize the frictional force and the cohesion of the soil nailing and the surrounding soil of oblique setting, soil mass consolidation forms assembly, makes soil structuresization, at the domatic steel mesh reinforcement of establishing of supporting, spray microlith and mix earth, making the local soil body at excavation face place and deep layer Stabilized Soil sports association is one, constitutes the supporting wall; This supporting and protection structure cost height, long in time limit, poor safety performance, influential to environment.
Summary of the invention
The purpose of this utility model provides that a kind of cost is low, the duration is short, security performance is good, environment is not had the elevator shaft foundation ditch supporting pine pile structure of influence.
The purpose of this utility model is achieved in that
Elevator shaft foundation ditch supporting pine pile structure, vertical and be arranged at intervals with pine stake guardrail at elevator shaft foundation ditch perisporium, the bottom of the elevator shaft foundation ditch in pine stake guardrail is equipped with the stone bed course, on the stone bed course, built the concrete bed course, the inwall that forms along pine stake guardrail in the elevator shaft foundation ditch is built brick wall fence, half place at the brick wall fence height is provided with the concrete collar tie beam, be filled with filling material in the gap between brick wall fence and the pine stake guardrail, built the concrete that bears down on one in the upper end of brick wall fence and pine stake guardrail and the upper periphery of elevator shaft foundation ditch.
The length of above-mentioned pine stake is 5.5～6.5m, and the degree of depth of elevator shaft foundation ditch is 1.5～3m.
The length of above-mentioned pine stake is 6m, and the degree of depth of elevator shaft foundation ditch is 2m.
Above-mentioned filling material is sand or rubble.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model is vertical and be arranged at intervals with pine stake guardrail at elevator shaft foundation ditch perisporium, reduced the influence of the long side effect of large-area foundation ditch, be filled with resistance to deformation, migration-resistant ability that yellow sand has improved elevator shaft foundation ditch wall in the gap between brick wall fence and pine stake, thereby having guaranteed that the elevator shaft foundation ditch re-uses in the process does not deform, and has improved the security performance of elevator shaft foundation ditch greatly.
2, the utility model adopts pine stake guardrail to go along with sb. to guard him, and cost is low, can directly with excavator the pine stake be pressed into elevator shaft foundation ditch bottom surface, and easy to use, the duration lacks, environment is not influenced.
